First release

This is the first release of arc-prototype. It is a full rewrite of arc\lambda\Prototype, included in arc-base. To provide support for observe/freeze/etc. properties are no longer saved as public properties in the object. This means that this version is slightly slower and cannot be easily exported to json. In addition if you use array properties, you must copy them, change them and then copy them back, since they are overloaded.

But in return you get the ability to use javascript like observe methods and freeze objects.
